grouping things make ones life easier by sorting them in their correct group by their similarities and differences.
grouping also makes it more easier for one to access his / her things
Grouping objects is an important organizational skill. You should group like objects to keep things orderly and easier to find or understand.
To remembering the properties of all elements in simplified way because elements some group show almost similar properties as they have similar outermost electronic configuration.
Things are put in groups for a few reasons but mostly for organization. Humans have an easier time dealing with groups and then the contents within those group more easily compared to simply having one large group with all of the contents. Things are also put into groups because it's psychologically easier for the human brain to sort by groups rather than by each individual content.
so that it is easy to study their chemical and physical properties
It is important to arrange elements in group because the elements are arranged in groups According to electron in outer most shell, So this arrangement tell which elements have same properties.
Because someone put them like that.

1. It makes it easier to find things when we need them.
2. It protect things to damage.
3. It store more things in less place.
4. It make the place beautiful when we put things orderly.
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
with group 17 elements or halogens
group 3 to group 12 elements
Do you own CA work!!
periodic arranging
they are grouped by there collums
All their electrons are in one orbital.
Dmitri Ivanovich Mendeleev.
elements
By arranging elements with increasing proton (atomic) numbers.
Henry G. J. Moseley
Steps of k-map include expressing the elements in a map and then arranging similar elements in the map.
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
A chemist called Dmitri Mendeleev created the best way of arranging all the chemical elements- the modern periodic table. He arranged the elements based on their groups, e.g group 1 = alkali metals etc. Protons and nuclei hadn't been observed in his day, so any estimations and predicted elements needed to be clarified in the future. Mendeleev's predictions were accurate- hence his legendary table still exists today. I just hope I've spelt his name correctly!
Moseley arranged elements according to atomic number.Mendeleev arranged elements according to atomic mass.
On the periodic table, the elements fall into groups (the vertical columns) which are often called families. The reason is that elements in a group are chemically similar to each other.
